UNI f A ENT Specification of Letters Patent.

I p si oniof a "safetyloek for locking the hammer, whereward into the breech of the gun."

One face of the breech block is f catej corresponding parts throughout the 'severaly1ews V I l The operatlng parts of ,the breech niech'a b tented Oct. 2,

anism are contained in thefcasing 1, "the" barrel being designated by the numeral- 2 v and the forwardstock section which inczlosesv the magazlne 3 is designated bythe numeral 4. The breech block 5 is mounted within .4

the chambered portion "of the casing and is shown in Fig. 2 in its locked position and in Fig. 3 is illustratedin the positionit assumes just prior to being; looked.

i The usual sliding "handle 46 is mounted Q upon the lower portion ofthe forward of the ,stockand is arranged'fto reciprocate the action bar T'which is mounted to have a" reelp'rocating movement within the recess 8 formed in the face ofthe ca'sing saidac} tion bar beingconnected by meansfof aipin- 9 passing through registering aperturesin the walls of the handleand connected to. the

action bar, said pinpassingthrou'gh elon'' gated registering slots 10 formediin the forward stock portion? and serving toguide the handle in the operationof the gun. The rear' end of the action bar is provided with a suitable aperture, whichengages the pin 11 which is carried flbythe i The breech block is provided with recesses breech locklng lever 12. The member 12jis 1 forked, forming two arms] 13 pivotally =mounted upon a pin '14; which passes through the breech blockmj a 15v upon opposite sides thereof in which the arms 13 of the breech lockingl'ever are positioned, the rear endof said lockin mem her having a hooked shaped projectionlti which serves as a means of protecting the firing pin 17 when the breech block is driven rearwardlyto receive ,a shell .to be red for with a recess 18 to receive a resilient shell i I n 9 provided extracting triggerfl9'. The locking rnember '12 is provided with a cam shaped projec tion QO'uponits free end which terminates a Thetilting shelllifting s ate 22 ispivotally mounted upon the .:pin23and is prof vided near its forward. free endgwit-han elongated slot 24, through which slota lift- M ing finger 25, pivoted at 26, is located,1the

purpose of this finger being to elevate the;

rear end ofthe shell while thc latteris be-j" the shelltobe released from the magazine when it is desired to deliver the' same into the barrel of the'gun.- Pivotally'mounted vupon'a pin 31 carried by the rear end of the shelllifting member is a pawl'32, a spring 33 bearing against the wall of'thef recess 84- and against the pawl to normally hold the pawl at its farthest inner throw so that the upper edge thereof'will bedeposited in the V path of the inclined shoulder 21 whenthef breech block is thrown back fromits for ward'position; allowing thepawl to swing; out idly, fwithout causing the shell lifting membert'o be tiltedQ y c It will be noted, that the pawlhas its upper rear edge inclined at 35 against which i the inclined edge 36 of the'cam shaped pro- 7 jectio'n 20 is adapted to contact as the breech block is movedfforward' 'from'its rear'mo stq position, thus causing the forward end f of' the shell raising "member to be thrown up for the purpose of raising a shell previously withdrawn-from the'magazine to a position. to be driven intothe barrel on the forward movement of the breech block. j, I V

During the tilting of" the shell raising member, the finger25jbefore referred tofis thrown to an inclined position and coming in contact with therear portion of the shell will 'tend'to liftjthe same up to a position in alinement with the barrel so as to avoid any possibility of the cartridge jamming when driven forward by'the breech block.

The breech block is driven forward and the projecting portion 37 thereof comes into contact with theishoulder 4:0 and a further forward movement of the sliding handlefi will cause the action bar to move therewith and asjtherear end of said bar is pivotally 7 connected with the locking block 12 the lat .c terwill becaused to swingfirst into'the posi-' 'tion illustrated in Fig; and then to the position shown in Fig; '2 with the convex or cam edge 41. of said; locking blockin contact with the upper edge of the lug .42, which-f is carried by the lower wall of the casing;

This swinging movement of the locking block will throw the rear endof thebreech block into the position shown'in Fig. 2 in which its upper end' will bear against the shoulder 44: thus J forming an abutment meansvfor the breechiblock. I

The hammer 4:5 is pivotally mounted upon a 'pin 4:6,;the lower part 47 of the hammer c with the lockingjof the breech block,

'bloc'k is moved forward in the an ear'54 atits upper extremity, the purpose of which'will' be later described. A

hammer spring 51 is fastened at one end to the bottom of the casing and engages a notch 52 formed in the edge of the hammer. The

hammerisprovided with a shoulder 53 on its rear sidewliich engages the shoulder 50 at the upper end of the trigger in the manner shown in Fig. 3 of the drawings, holding the hammerin the cooked position. i

The forward end .of the shell lifting'lever 22 is slightly inclined asfat 55 and is designed to engage and depress the shell hold-' v ing member 27 when the breech blockis atits forward limit to allow a shell to be driven by the spring plunger '56f'within the magazine toa position to be raised by saidshell lifting member." This action of the tilting'shell lifting member to release a shell 7 in" the magazine by the depression of the member 271is' snbstantially simultaneous The side of thecasing' is provided with an opening 60 through'whlch opening the shells are placed within the leasing asthey'are fed into the magazine and through which open-v ing the shells arefthrown' out after being fired. iA 'closure 62 to said "opening is fastened to the breech block andmoves therewith. and automatically opensas the breech block is thrown rearward and closes as the V w .c c of i (r the shell into the barrel. Y lt should be noted that upon the forward movement of the 'sliding' handle .it will be impossible for the hammer'to' strike the fir-. ing pin by reason 'ofthe hooked shaped projection 16, ofthe locking member forming an abutment surface against which the ham? mer wouldcontact, thus producing a safety device which will positively insure the hammer against. engaging the firing pin until the" 11 breech} block and breech loelnng member have assumed theposition'shown in Fig. 3. In this position the breech isinot quite locked and it would be possible fOrLthe'hammer to' contact with the'firing pin'discharging the shell with the breech unlocked,which would not only probably damage the gun but would be exceedingly dangerous to theperson fir ing the gun orthose near byQQ In order: to prevent accidental discharge of the shell at any tim'e'while theb'reech block and breech lockingmember are in any position between j that shown in Fig..3 and the locked position shown inFig. 2','a"s'afetyfdevice isprovided,
